Using remix billing API to set calculated trial days

[andrew_upo]

Hey, everybody!
I don't know where to turn, so I'll write here. I would like to get clarifications from the developers of Billing API.
1. In the documentation on using billing API for remix it seems to be a mistake, lineItems is specified as an array, but written as an object (see screenshot).

2. Can I write billing plans in shopify.server.js, and then on pages in action when calling await billing.require(...) pass here the calculated number of test days?
For example, if a user installed an app, got a trial period of 10 days, uninstalled the application after 3 days, so that the next time he installs it, I can give him only 7 days of trial period, but all 10.
Or is it necessary to use only GraphQL queries for such a case?

I realized that I can pass the calculated trial days to the function for remix.

await billing.require({

      plans: [plan],

      isTest: true,

      trialDays: calculatedDays,

      onFailure: async () => billing.request({ plan: plan, isTest: true, trialDays: calculatedDays, }),

      returnUrl: ``,

    });

@andrew_upo where did you give calculatedDays value?
